ln so far as l ani at present aware, no one has ever before provided a stud and socketfastener having a rounded shoulder which could not be disengaged by a-suficiently strong rectilinear relative pulling apart of the stud and socket. lt is among the objects of this invention to provide a socket which, When coperating ivith a stud having a rounded shoulder, cannot be separated from the stud Without a relative tipping movement. lpreferably limit this tipping move- Specification of Letters Patent.

nient to one direction so that, for instance,

(Fig. 2) the socket can only befseparated from the stud by an outward pull on the lower portion of the socket. Itis of course obvious that corresponding. relative nipvement may be obtained by similarly moving the stud in the` opposite direction. Another object of the invention is' to provide a stud and socket fastener having a positive jawcoloperating With a yielding jaw so that the 'strainr is. taken by the solid or fixed jaw rather than by the yielding avv, and of such i construction that When the socket is in the proper relative position to the stud, separa-i tion of socket and stud can only be produced by a ltipping movement, even if the spring jaw were removed.

.ln the illustrative socket l have provided a front casing 2O having a portion thereof stamped out to provide an aperture for the head of the stud, and a portion of what is usually stamped out-'for such aperture'v pressed inwardly to provide fixed jaw 21 opposite a yielding jaw 22, which maybe andpreferably is in the general form shown as 23 in Fig, 3. The fixed jaw 2l and the yielding javv 22 are preferably substantially opposite one another, and the relation between the fixed javv 21 and the rim 24 of the aperture in thefront plate 20 opposite the fixed jaw are preferably so positioned relative to each other and relative to the head ofthe stud that a direct rectilinear pulling apart of the socket and stud Will result in one side of the shouldercofthe stud catching on the fixed jaw 2l, whilethe other side of the stud on or beyond the shoulder will abut on the rim 24e of the front plate 20.

l may 4and preferably do also position the' fixed jaw relative to the aperture in the plate 2O and relative to the head of the stud so that any tipping movement transversely of the liXed jaw 21 Will bind the stud between the sides of the fixed jaw and the out the cooperation of the back plates of the socket, which preferably have a guiding and limiting function, and which are preferably adapted to relieve the front plate 20 of a considerable proportion of the strain placed thereon by a tipping movement in an undesired direction. `When the stud and socket are tipped apart at the bottom viewing Fig. 2, however, the springjaw' may yield and ride over the curved camli'ke part of the head so as to permit the two elements to be separated.

I have shown the front plate attached to an intermediate plate 25, fabric 26 and back 4plate 27 by prongs 28, preferably integral with the front plate 20. While I have shown'the prongs 29 (Fig. 3) as closed on the spring 23 and not passing through the intermediate plate 25, I may, if desired, provide suitable apertures in the plate 25 and bend the prongs on the back side of the plate 25, thereby clamping the front plate, spring and back plate together prior' to the closure of the prongs 28. The intermediate plate 25, fabric 26 and back plate 27 are preferably pierced by a hole slightly larger indiameter than the enlarged shank of the stud 4, the enlarged portion of such 'shank extending within the aperture. The aperture is preferably-centric and round, and of just sufficient size to permit the tipping operation in the desired direction.

Vjaw is preferably always located at the top of the fastener, because it is for mostl purposes-more convenient to lift the bottom portion of the plate than to pull down the upper portion.v

It is also clear that the aperture of the front plate 20 may take'various forms, in vsome of which merely an indent'and not a hole would be provided.

Vhile for` illustrative purposes I have I shown and described one embodiment of my invention, it is obvious that changes involvmg omlssion, substitution, alteration and reversal of parts, and even changes in the mode of operation, may be made without departin from the scope of my invention, which 1s best defined in the following claims.

Claims: 1. A stud and socket fastener comprising, in combination, a stud having a head providing a sloping shoulder and a socket providing opposed jaws, one resilient, the other fixed, positively opposing rectilinear withdrawal of said stud from said socket, while permitting withdrawal thereof when said stud and socket are tipped one relative to the other.
